A trough feeder system has a plurality of troughs connected with couplers to prevent the troughs from rotating relative to each other. Each coupler has at least one sidewall stop protruding inwardly from a sidewall that limits the distance the trough can be inserted into the coupler. The coupler has a central catch generally above the sidewall stop and a pair of outward catches, wherein the central catch and one of the outward catches capture each trough at different positions along the longitudinal axis of the trough so as to prevents the trough from rotating relative to the coupler and also the adjacent trough being held by the coupler.
